Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed June 3, 1916. Serial No. 101,504.

To all whom it may concern:

Be known that I, THOMAS E. MUR- RAY, Jr., a citizen of the United States, re-

' siding at Brooklyn. in the county of Kings and State of New York, haveinvented a certain new and useful Improvement in Switches, of which the following is a specification. i

The invention relates to switches, and consists in the construction whereby a fuse is carried on the switch lever and the cooperating contacts are simplified.

In the accompanying drawings- Figure 1 is a plan view of my switch.

Figs. 2 and 3 are'sections on the line :12, m of Fig. 1. Figs. 4 and 5 are sections on the line y, y of Fig. 1'. In Figs. 2 and 4: the

- switch isshown open, and in Figs. 3 and 5 the switch is shown closed.

.Similar numbers of reference indicate like parts.

1 is an inclosing case. 2 indicates, generally, a meter or any other translating device in. circuit with the switch. 3 is a base block, preferably of insulating material, on which are contacts 4, 5, respectively con nected to the meter leads 6, 7. Also on said block are contacts 8, 9 connected by metal itwo pairs of spring clips 18, 19.

strips 10 to supply leads 11, 12.

The switch lever 13 is of insulating material, and is secured at one end to the rocking bar 1 1. One extremity of bar 14 is pivoted in bracket 15. The other extremity is supswitch lever 13, Figs. i and 5, is a contact plate 20, not connected to said clips. The usual metal ring terminals of a fuse 21 of the cartridge type are seated in the pairs of contacts 18, 19.

lVhen the switch lever is closed, F igs.

and 5, the lever contact plates 22, 23 cooperate respectively with fiXed contacts 1,8, and the lever contact plate 20 cooperates with fixed contacts 5, 9thus establishing circuit, which proceeds from supply lead 11, through contacts 8, 22, to fuse 21, through said fuse to contacts 23, 4, to translating device 2, and thence to Contact 5, contact plate 20, contact 9, and supply lead 12.

I claim: 1. A swltch, comprising two pairs of fixed contacts, a pivoted switch lever, contacts on said lever respectively cooperating with one member of each of said pairs of fixed contacts, a fuse on said lever having its terminals connected to said lever contacts, and a contact on said lever cooperating with both remaining members of said pairs of fixed contacts.

2. A switch, comprising two pairs of fixed contacts, a pivoted switch lever, two spring clips on the outer face of said lever, contacts on said lever respectively connected to one member of each clip and respectively cooperating with one member of each of said pairs of fixed contacts. a fuse removably seated in said-clips. and a contact on said lever cooperating with both remaining members of said pairs of fixed contacts.

In testimony whereof I have atfixed my signature in presence of two witnesses.
